REGISTER non LIQUID-DISPENSING APPARATUS.

Original application filed November29, 1924, Serial No. 752,837. Divided and this application filed May To all whom it may concern;

Be 1t known that I, WIL IAM L. MARDEN, a citizen of the United States, resid ng in the borough of Queens, of the city and State of New York, have invented certain new and useful Improvements in Registers for Liquid-Dispensing Apparatus, of which the following is a specification, reference being had to the accompanying drawing, forming a part hereof, this application being a division of application Serial Number 752,837, filed November 29, 1924.

This invention relates to devices by which the quantity of a liquid dispensed, asat a gasoline filling station, is indicated to the purchaser in units or fractions of units of volume or multiples thereof, while registration is also made, if desired, of the total volume delivered. It has for its object the provision of simple and compact mechanism -which will indicate or register the volume of liquid dispensed at each sale or operation in the fraction of the unit volume or in multiples of the unit volume or both and after each sale or operation can be setback readily to zero in readiness for another operation. The invention will be described more fully hereinafter with reference to the accompanying drawing ill which it-is illustrated and inwhich- Figure 1 is a view in side elevation of the registering devices, the casing of'such .devices and the casing of the upper portion of the metering device being shown in section on the plane indicated by the broken line 11 of Figure 2. 4

Figure 2 is a view of the registering mechanism in elevation as seen from the right hand in Figure 1, with the casing invertical section on the plane indicated by the broken line 22 of Figure 1.

Figure 3 is a View of the parts vshown in Figure 1 as seen from above, below the plane indicated by the broken line 3-3 of Figure 2, without the casing.

Figure 4 is a detail view of the set-back hand shaft and some of its ap urtenances.

Figure 5 is a detail view 0 the cam stop plate with the shaft in section on the plane indicated by the broken line 55 of Fig- .ure 4.

in section on the plane indicated by the broken line 66 of Figure 4.

In the embodiment of the invention illustrated in the drawing there isvshown at a a portion of the casing of a disc meter of well known construction with which thev improved registering devices are associated and from which they are driven through a shaft 1) which is in engagement with the metering mechanism to be rotated thereby. The shaft 7) is mounted in hearings in a frame 0 which receives and supports the registering mechanism. A casing 03 encloses the registering mechanism and supports a dial cl for co-operation with the pointers or indicator hands hereinafter referred to.

The shaft 6 through a worm and worm gear indicated at 6 drives a totalizing regis ter of ordinary construction indicated at f, by which the total number of units of vol ume of liquid dispensed in successive operations is registered. The shaft 6" also carries a worm or skew gear 6 which meshes with the corresponding worm or skew gear 9 which is mounted frictionally on a. shaft in Through a clutch 2', preferably a ball clutch, 9

cator hand it" which makes a complete revolution for each unit of' volume of liquid which passes through the metering device, indicating by its position also a fractional part of the unit volume. The shaft it also carries in front of the dial and in front of the protecting glass (Z a knob or handle 71,2 by which the unit pointer can be turned back to zero position after each operation.

Fixed on the shaft k is a pinion '5 which meshes with'a gear k on a counter shaft is. A pinion on the shaft k 'meshes with a gear is on a sleeve 70* which is mounted loosely on the shaft h and carries, in front of the dial (2', a pointer or indicating hand is". The gears z, k, k and k? are so proportioned that for every complete revolution of the pointer h the pointer k advances over one division of the scale formed on the dial whereby, for any operation of the reg; istering mechanism, the pointer 70 will registe g'the. total number of gallons or other units of volume dispensed and the pointer it will register the fraction of a unit of volume.

In order that the pointer 74 shall be set to zero in the same operation with the setting ofthe pointer h there is fixed on the shaft k a pawl carrier it on which is mounteda spring pressed pawl 5. adapted to engage a cam stop plate/h which is fixed on the sleeve k of the pointer 70 the pawl coacting with the shoulder of this cam plate so that as the shaft h is turned by hand towards zero the pawl h engages the shoulder of the cam stop plate and the sleeve k is turned with the shaft h. To insure the bringing of the pointers to rest at the zero position there is carried with the cam stop plate k a second cam stop late It", with its shoulder o ositely placed,

P PP

so thatwhen the pointers reach the zero position the shoulder of the cam stop plate it will be engaged by a stop pawl h and prevented from movement backward beyond the zero position. To permit the operation of setting back it is necessary that one of the gears of the train, such as the gear 70 shall be frictionally mounted so that it may move during the operation of setting back although other parts of the gearing are necessarily restrained from motion through the resistance offered by the worm or skew gears.

The operation of the several parts of the improved structure has been set forth in connection with the description of the detailed construction and no further explanation of the operation of the structure as a whole is necessary.

I claim as my invention:

1. In a registering mechanism comprising a driving shaft, a unit indicator shaft carrying a unit pointer and having a resetting handle, and a-skew gear on the driv ing shaft, a gear mounted loosely on the indicator shaft to co-act with said skew gear, and a clutch interposed between the loosely mounted gear and the indicator shaft to transmit rotation to the indicator shaft and to permit it to be independently rotated.

2. In a registering mechanism comprising a driving shaft, a unit indicator shaft carrying a unit pointer and having a resetting handle and transmitting gearing between the driving shaft and the indicator shaft, a clutch forming a part of said gearing adapted to transmit rotation'to the indicator shaft and to permit it to be indedependently rotated, a sleeve mounted on the indicator shaft and carrying a pointer, reduction gearing between the indicator shaft and said sleeve, a pawl and a stop cam carried by the indicator shaft and the sleeve,

a second stopcam carried by the sleeve, and a stop pawlin operative relation with said second step cam.

3. In a registering mechanism compristween the driving shaft andthe indicatorshaft, a clutch forming a part of said gear-- ing adapted to transmit rotation to the indicator shaft and to permit it to be independently rotated, a sleeve mounted on the indicator shaft and carrying a pointer, a pinion on the indicator shaft, a gear mounted frictionally on the sleeve, and aparallel shaft having a gear in engagement with the pinion on the indicator shaft and a pinion. in engagement with the gear on the sleeve.

4. In a registering mechanism comprising a driving shaft, a unit indicator shaft carrying a unit pointer and having a resetting handle, and transmitting gearing between the driving shaft and the indicator shaft, a clutch forming a part of said gearing adapted to transmit rotation to the indicator shaft and to permit it to be in- .dependently rotated, a sleeve mounted on and the sleeve for resetting, and a stop cam and a co-acting pawl on the sleeve and indicator shaft.

5. In a registering mechanism comprising a driving shaft, a unit indicator shaft carrying a unit pointer and having a resetting handle, and transmitting gearing between the driving shaft and the indicator shaft, a clutch forming a part of said gearing adapted to transmit rotation to the indicator shaft and to permit it to be independently rotated, a sleeve mounted on the indicator shaft and carrying a pointer, a pinion on the indicator shaft, a gear mounted frictionally 'on the sleeve, a parallel shaft having a gear in engagement with the pinion on the indicator shaft and a pinion in engagement with the gear on the sleeve, means to couple the indicator shaft and the sleeve for resetting, a stop cam and a co-aeting pawl on the sleeve and indicator shaft, a second step cam on the sleeve, and a stop pawl in operative relation with said second stop cam.
